I'm not that sure since I am doing a science assignment on seafloor spreading but, I think I've got a pretty good grasp on 5 steps
Magma pushes up through the Earth's mantle and breaks through the crust.
Magma flows outward in the ocean in all directions and hardens to form new ocean floor by the ridge.
New ocean floor pushes the old floor away from the mid-ocean ridge
The old floor then pushes the continents away from the ridge
Lastly, the old ocean floor is forced under the continental plate, and melts back into magma.

The modern seafloor spreading rate range is between 1 to 10 centimeters per year. This rate varies depending on the location of the mid-ocean ridge where the seafloor spreading is occurring.
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
Oceanic currents themselves do not directly cause seafloor spreading. Seafloor spreading is primarily driven by tectonic forces, specifically the movement of tectonic plates away from each other at mid-ocean ridges. This movement leads to the upwelling of magma from the mantle, creating new oceanic crust at the spreading center. Ocean currents can affect the distribution of heat and nutrients in the ocean, but they do not play a direct role in the process of seafloor spreading.
Magnetism is used to support the theory of seafloor spreading through the study of magnetic stripes on the seafloor. These stripes are aligned with the Earth's magnetic field and provide evidence for the process of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges. As the crust cools and solidifies, the magnetic minerals in the rocks align with the Earth's magnetic field, creating a record of magnetic reversals over time that support the theory of seafloor spreading.

They proved that the seafloor was spreading.

Seafloor spreading is triggered by a rift in a continental land mass.
Gravity in the oceanic crust is responsible for seafloor spreading.
The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of seafloor spreading.
Seafloor Spreading helped move the Continents to their current location.

No, seafloor spreading does not hold the plates in place. Seafloor spreading is a process that occurs at mid-ocean ridges where new oceanic crust is formed and spreads apart. It is driven by the movement of tectonic plates, which are actually responsible for holding the seafloor in place.
Magma plays a key role in seafloor spreading as it rises from the mantle through the mid-ocean ridges, creating new oceanic crust. This process involves the formation of new crust as magma cools and solidifies along the spreading center, pushing the existing seafloor apart.
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
We can't feel seafloor spreading because the ocean is super deep that the continents will not shake or burst in somewhat actions.
